Composition of matter resembling celluloid.



ED STATES PATENT OFFICE- OTTO SCHMIDT, OF LUDWIGSHAFEN-ON THE RHIN E, GERMANY, ASSIGNOR TO BADISGHE ANILIN' & SODA FABRIK, OF LUDWIGSHAFEN-ON-THE-RHINE, GERMANY, A CORPO- COMPOSITION OF MATTER RESEMBLING CELLULOID.

BATION.

j gm ggfi Specification of Letters Patent.

No Drawing. Application filed October 21, 1914. Serial No. 867,714.

acetyl cellulose, and also an acyl compound of a completely hydrogenized aromatic amin. The acyl compounds of completely hydrogenized aromatic amins are easily obtainable on a large scale, and they are very efiicient in causing the nitrocellulose, or

other derivative of cellulose, to swell, and v in dissolving it. The masses obtained are odorless and colorless, and have but small specific gravity and excellent stability against the action of heat and light.

The following examples will serve to illustrate further the nature of this invention,

which, however, is not confined to these examples. The parts are b weight. a Example 1: Mix toget er thirty-five parts of acetyl-dicyclo-hexylamin (which possesse's the formula and can 1.. obtained byacetylating the dicyclo-hexylamin, described by Sabatier and Senderens, Oomptes Remius vol. 138, page 458) and eighty-two parts of nitrocellulose together with a little alcohol, and then work up the mixture. A very fine, colorless celluloid-like product is obtained.

Example 2 Dissolve thirty parts of acetyldicyclo-hexylamin and seventy parts of acetone-soluble acetyl-cellulose in a mixture of alcohol, acetone and ethyl-methyl-ketone, and work up the solution. A fine transparent colorless celluloid-like product is obtained.

Example 3: Mix thirty parts of para-toluene sulfo dicyclo hexylamin (obtainable from dicyclo-hexylamin by the action of Patented Oct. 10, 1916..

para-toluene-sulfo-chlorid) with seventy parts of nitrocellulose in the presence of alcohol, and work up the mixture. A fine flexible celluloid-like product is obtained. Now what I claim 1s:-

1. A new composition of matter resembling celluloid containing a cellulose ester and an acyl compound of a completely hydrogenized aromatic 2. A new composition of matter resembling celluloid containing a cellulose ester and acetyl-dicyclo-hexylamin.

3. A new composition of matter resembling celluloid containing nitrocellulose. and

' acetyl-dicyclo-hexylamin.

In testimony whereof I have hereunto set my hand. OTTO SCHMIDT.
